W166 M-Class reliability - better info
I wanted more up-to-date car reliability information that made the differences between cars clearer. So a few years ago I started getting people together to make this possible. TrueDelta now updates actual repair frequencies, not just dots, four times a year, to provide initial stats on new models sooner then track cars closely as they age.
Thanks in part to the help of members of this forum, for which I'm very grateful, we provided initial reliability stats for the 2008 C-Class and 2010 E-Class well ahead of any other source. I'd love to do the same for the W166 M-Class, just a matter of how soon enough owners get involved.
Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, following the end of each quarter.
To encourage participation, participants receive full access to all results, not just those for the M-Class, for free. I'll share results for the W166 in this thread after each update.
